Title: Retention article for electrical contacts
Inventor: RUDY WILLIAM
IPC: H01R4/24
Filed: 1985-06-24
Granted: 1989-01-19
Abstract: The retention article has a stiff article of thermoplastic material surrounded by elastomeric material, with holes. A pair of arcuate, wall sections partly surround each hole having forward ends acting as stop surfaces to engage a stop shoulder on each inserted terminal. Elastomeric material forward of the planar section surrounds the wall sections, so that when a terminal is inserted into a hole of the retention article it slightly expands the walls apart until the shoulder passes the forward ends. Elastomeric material rearward of the planar section has holes having a diameter slightly smaller than conductors on terminals inserted to grip the conductors. The elastomeric material permits a slender extraction tool to be inserted along a conductor, expanding the material, and then urging the ends of walls and adjacent material around the terminal to release the terminal which is then withdrawn rearwardly along with the tool from the connector.

Abstract: A synchronous ac electrical motor comprising (A) a stator (20) having a body slotted (30), soft ferromagnetic, low eddy to produce a rotating magnetic field, an excitation coil (32) energizable with single phase ac located in two adjacent slots with a pole piece between them, and feedback windings (33) located in slots such that when ac potential therefrom is conveyed to the excitation coil the excitation ac is modified to a selected phase and magnitude to improve the "pull in" torque of the motor, a capacitor (94) containing circuit connecting the feedback windings and the excitation coil, the body of ferromagnetic material having a cylindrical surface, and the improvement characterized in that (B) a rotor (40) has three major components electrically and magnetically associated, (1) first being an exterior layer (52) low electrical conductivity magnetizable permanent magnetic material having an outside cylindrical surface complementary to that of the stator, (2) a high-permeability, low eddy current component (44) to which the first layer is attached, and (3) the third component (48) being a supporting body of ferromagnetic material of high permeability and high electrical conductivity on which the second component and first layer are fixedly supported. The third component can be a solid ring of steel, for example, or it can be a laminated core containing shorted electrical conductors. In starting from standstill, the power windings and energized with ac power and this produces a circulating electrical current with the third component of the rotor which reacts to produce rotational torque. After the rotor reaches about 70 to 80% of synchronous speed, the excitation coil is energized and this will produce strong alternating magnetic flux in the pole piece (34) which magnetizes the layer of the permanent magnetic material into a pattern of north and south magnetic poles in the proper phase with the rotating field of the stator so as to produce a powerful rotational torque that accelerates the rotor to a predetermined synchronous speed.
